So sorry to hear of Cliff's death. My sincere condolences to you Bill, and to the rest of your family. I hope that the really great affection and respect for your father felt among the membership of PPRuNe is of some consolation to you. This thread stands here as his memorial, and to all of his compatriots including those now posting and those who are yet to do so. He fearlessly tackled the IT challenges of posting, including the all important visual evidence from photos and logbooks, as he did with every new challenge and opportunity. He indeed lived life to the full, and is an example to everyone, and not only aircrew, as to how to live a good life. I may not have had the privilege of meeting him, but feel grateful to have learned so much from him on the pages of this thread.
RIP Cliff, now up in the wide blue yonder...
